短暂性脑缺血发作(TIA)和脑梗死是神经科的常见急症。TIA与脑梗死的关系主要在于两方面:一方面TIA可以进展为脑梗死,另一方面TIA又能改善继发性脑梗死的预后。随着神经科学的发展,人们对TIA与脑梗死的关系有了更深入的认识。国外的学者除了呼吁废除传统的TIA定义以外,对TIA后卒中发生率,如何预测TIA后的脑梗死风险,以及TIA诱导的神经保护机制都做了一定的研究。本文就将结合国内外的一些研究新进展探讨TIA与缺血性卒中的关系。
Transient ischemic attacks (TIA) and cerebral infarction are common neurological emergency. The relationship between TIA and cerebral infarction lies mainly in two aspects: on the one hand TIA can progress to cerebral infarction, on the other hand TIA can improve the prognosis of secondary cerebral infarction. With the development of neuroscience, people have a deeper understanding of the relationship between TIA and cerebral infarction. In addition to calling for the abolition of the traditional definition of TIA, foreign scholars have done some research on the incidence of post-TIA stroke, how to predict the risk of cerebral infarction after TIA, and the neuroprotective mechanism induced by TIA. This article will be combined with some new research progress at home and abroad to explore the relationship between TIA and ischemic stroke.
